Swift made Sport Springs keeps the quality ride you get from the showroom, and adds improved handling and lower ride height for driving enthusiasts and style minded drivers who demand only the best.

Swift did not develop the Sport Springs line by simply dropping the ride height. Unlike other manufacturers whose sole focus was style, Swift approached the creation of these lowering springs with 3 goals.

  1. Maintain or improve a smooth, comfortable ride.
  2. Increase handling by reducing body roll and squat in search of overall suspension balance.
  3. Lower the vehicle within tolerance of each vehicle's usable stroke

Every cars have their usable strokes

Most enthusiasts have had experiences with the typical harsh and uncomfortable ride from lowering springs. Performance is often overlooked by manufactures simply because it is easier to lower a vehicle for aesthetics. The end result is usually a bumpy ride that causes a decrease in traction, or excessive worn shocks caused by lowering the vehicle beyond the usable stroke.

Proprietary material and design to satisfy two contrasting factors

As you can imagine, keeping or improving the comfort level while increasing performance is not an easy task, especially since these two aspects contrast with each other.

Where most of the competition simply gave in to the easier method, Swift Springs decided to tackle this issue by creating our own material (H5S.TW), and unique manufacturing method that works very well for this material. Working in unison, the material and manufacturing method provides a superior level for both comfort and handling.

The way we design the lowering springs

We utilize spring design with fewer coils which not only allows us to decrease un-sprung mass but to also completely eliminate the chance of coil bind, while increasing the amount of usable stroke. Our proprietary material (H5S.TW) has a much quicker transient response, reacting to any road conditions which, in turn, cause a much smoother ride where other springs will skip on the harsh road surface, our spring will react to the road surface as needed.

With the Swift Sport Springs, we expect both street and circuit users to experience an increase in all aspects of suspension tuning from performance to comfort.

Bump Rubber

Suspension usable stroke for the cars now a day is very limited compared to before. To let the suspension do its own job efficiently, many car manufactures use bump rubber as a part of a suspension's functional part, not only to limit the shock stroke but to prevent the shocks from bottoming out. This scenario also applies to real world racing, and we use this as a primary focus when designing the sport springs.

Vehicle characteristics

Swift developed each Sport Springs application based on the individual vehicle's unique characteristic. Put simply, a luxury car will maintain its luxury ride, and sports car will maintain its sports car feel.

Note: Vehicle drop rate is based on the year, model and option of the test vehicle, and may vary based on each vehicle condition.
All the specs above are subject to change without any notice.

Suspension

We have suspension kits, shocks and struts, strut rods, control arm, disc brakes, lowering springs, tie rod end adjusting sleeves, you name it we've got it.

Car & Truck suspensions also are crucial for providing stability on the road. Since these vehicles are heavier and might also be carrying additional weight, the suspension must be able to assist with handling uneven roads. The suspension also helps prevent trucks from tipping. The suspension also needs to help cushion the ride so the cargo and equipment remains protected over bumps and other imperfections in the road. Cushioning the ride also helps improve driver comfort. The suspension allows the tires and axles of the truck to move independently from one another, instead of the axle being attached to the frame directly. This helps soften the impact to the vehicle and helps absorb the impact of cracks, bumps or dips in the road

Swift Springs

Swift Springs was founded in 1997 in Tokyo, Japan as a motorsports division of Tokyo Hatsujo Manufacturing Co, Ltd. that has been leading the spring industry since 1924. Their first-hand involvement within the race industry has propelled Swift quickly through the ranks of some of the world’s most reputable races. Swift Springs quickly became one of the most recognized and respected name in performance coil springs in many genre of motorsports throughout the world. The purpose was to demonstrate superior engineering in spring by developing the next generation of motorsports suspension coil springs. They had to have the best characteristics of any brand or design in the market, which required the springs to be the lightest in weight and most durable, and to exhibit the most linear characteristics while still being cost effective.
